C064F code meaning
Brake Pressure Sensor N Circuit Low
What C064F means
C064F: sensor N reports less than its smallest valid signal. In integrated units the sensor element and its evaluation are split: Continental Teves fits a bare measuring bridge into the hydraulic block and leaves amplification and offset to an IC in the module, while Actronics, which repairs such units, names the ATE MK60 with its internal pressure sensor as the system with the most pressure sensor problems and recommends repair or replacement of the unit rather than of a single sensor. A low reading can thus come from the sensor, the contacts or the module input. GM's 2016 hybrid brake module, for comparison, sets the low code of its left rear wheel pressure sensor below 0.3 V within 0.1 s. Nobody documents C064F or the letter N.
C064F at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C064F
- ABS/ESC warning lamp on
- Stability control unavailable
Common causes of C064F
- Most likelyInternal pressure sensor of the hydraulic unit failed
- PossibleSignal contact or line shorted to ground
- Less likelyEvaluation IC in the control module defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4F | The exact fault in that area. |
What to do next
- Note C064F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C064F
What does C064F mean?
C064F means "Brake Pressure Sensor N Circuit Low". C064F: sensor N reports less than its smallest valid signal. It is a generic code, so it means the same on every make.
Is it safe to drive with C064F?
Drive gently and only to a workshop. With C064F the car can go into limp mode (reduced power) to protect itself.
Will C064F fail an emissions test?
C064F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C064F to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will C064F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
